Node deployment plays an important role in the design of wireless sensor networks (WSNs). Many important properties such as coverage, connectivity, data fidelity and lifetime are directed influenced by the way nodes are placed in the sensor field. In this work we show that the use of a stochastic point process, namely the C model, is able to increase the network lifetime by addressing the “ener...

Wireless sensor networks (WSNs) have attracted a lot of recent research interest due to their applicability in security, monitoring, disaster relief and environmental applications. WSNs consist of a number of low-cost sensors scattered in a geographical area of interest and connected by a wireless RF interface. Sensors gather information about the monitored area and send this information to gat...

Target tracking is one of the most important applications of Wireless Sensor Networks (WSNs). In this application, a large number of sensors collaborate in the detection and tracking of a target object(s). Because sensors are equipped with non-rechargeable batteries, a key design objective in such applications is to extend the network lifetime while maintaining an acceptable quality of monitori...

Accurate information is most important in Wireless Sensor Networks (WSNs). Incorrect (faulty data) information makes wrong decision; it decreases the reliability in communication. Fault tolerance is one of the issues in WSNs .Proposed fault tolerant data aggregation scheme for identifying the faulty data sent by the sensors to the cluster head, where the aggregation is performed. Identified fau...

Wireless sensor networks (WSN) are generally distributed independent sensors which work mutually to monitor all or some physical or ecological conditions, such as temperature sound, pressure, moisture, humidity etc. They are sometimes called as Wireless Sensors and Actuators Networks (WSAN) as well. Wireless Sensor Networks work thoughtfully to pass their information through the network by capa...

Sensory hair cells rely on otoferlin as the calcium sensor for exocytosis and encoding of sound preferentially over the neuronal calcium sensor synaptotagmin. Although it is established that synaptotagmin cannot rescue the otoferlin KO phenotype, the large size and low solubility of otoferlin have prohibited direct biochemical comparisons that could establish functional differences between thes...

Protracted elevation in intracellular calcium caused by the activation of the N-methyl-d-aspartate receptor is the main cause of glutamate excitotoxic injury in stroke. However, upon excitotoxic injury, despite the presence of calcium entry antagonists, calcium unexpectedly continues to enter the neuron, causing extended neuronal depolarization and culminating in neuronal death. This phenomenon...
